In the development of one of'theunit members, the sameis formed by taking a and width and providing it, by suitable i means, With a number of iins or plaits 10 and a number ofrbeads f the said beads and plaits being alternately arranged: l

In my construction of plait the opening orblind passage formed in bending up the 'plait is of greater area at a point midway the length of the said passage, as indicated by Fig. 7, and from the said point the passage gradually tapers 'toward each end andv is closed at tlievends by reason of the two opposing Walls' ofthe plait being pressed against each other. The closed' end of the plaits terminate some distance from the opfluid passages in the plaits are threeand one-half inches long, the opposite walls at the ends being closed flat against each other to the extent of one-.fourth of an inch at each end.' At the center, the Huid passages are one-eighth of 'an inch Wide and tlie said passages gradually taper in their. width from the center to their closed ends.

The spacing beads or corrugations f that alternate with the plaits, are shaped like the blind passages, with their. ends terminating `in line with the ends of the blind lpassages,-a short distance away from the opposite edges of lthe strlp, as 1s clearly*y shown at 2 2.

By reason -of forming the corrugations and the blind passages inthe manner described and shown, a greater .cross sectionalarea of surface is provided at the opposite ends ofthe air passages than aty the center of said passages, yas indicated by la--zi on Figs. 2, 3 and 6, and a'suiicient beaded or corrugated surface is maintained, for holding the units separated for thewater circulation.

Again, by maling the corrugations or beads tapering and stopping'their ends short of the opp'osite edges ofthe metal strips sulicient bearing surface-is provided -for holding the units separated and in addition the cooling surface between the ends of'each pair of adjacent plaits is further lincreased as indicated at c--c.

To further add rigidity to the assembled radiatorunits the outer orl bearing edges position being Ashown in l Athe plaitshaving from the center toward the ends and termi formed on the opposite with the ends of the blind passages in the plaits, the opposite ends of said units having osets toproduce the vertical riiuid pasof the vtins or as indicated by 10a ,(see Fig. 7.). such shappl'aits lare slightly convexd,

The edgeso the units With the usual offsets l()X pose of enlarging the front and rear edges air conduits is pro may be provided .for the'usual purof the unit whereby a plurality-of vertical comprising a plurality of units arranged side by side in upright position, plaits formed on the opposite walls of each u nit, the plaits on-one `,vall extending across and abutting the opprosite ivall,the Walls' between adjacent vplaits being 'corrugated'or beaded-to forni spacers to separate the units, blind passages 'that taper nate short of the opposite end edges of the unit, the opposite edges of the units having Volisets to produce upright Water passages.

2. In a radiatorfa honey-comb structure comprising a plurality of units arranged side by side in an upright position, plaits Walls of 'eachunit, the plaits on one Wall extending. across and abuttin'g'the opposite Wall, the Walls between adjacent plaits being corrugated or beaded to form spacers to separate the units, the plaits havingblind passages that taper from the center toward the ends and terminate short of the opposite end edges of the unit, the corrugations or beads tapering in Width fromthe center to their'ends and with the said ends terminating short of the opposite end edges of the unit, the opposite edges of the units having offsets to produce upright waterypassages.

In a radiator construction, a radiator unit comprising t\vo.side Walls, each side Wall having plaits that extend across and abut the Aopposite side wall, the plaits'on the ioo oppositel side walls being alu-:rnately'dis`T i posed, the Walls between adjacent plais being corrugated .to form spacer bead for separating adjacent units, said plaitsA tapering in Width from their center toward their l endsLsaid spacer beadsftapering in .width from `their center toward their ends, and having their ends terminating in a,l1ne

In a radiator, the combination with a receivingand a. dispensing chamber; of a lao radiating body comprising a honeycomb structure embodying a plurality of units arranged side by side in an upright position, plaits formed on the opposite walls of the unit, the plaits on one wall extending across and abutting the opposite Wall, the Walls between adjacent plaits being corrugated or beaded to form spacers to separate the units, the plaits having blind passages that taper from the center toward the ends and terminate short of the edges o the unit, the outer edges of said units having offsets to produce upright water passages.

5. In a radiator, a honey-comb structure comprising a plurality of units arranged side by side in an upright position, plaits formed on the opposite walls of the units, the plaits on. one Wall extending across and abutting the opposite wall, the walls between adjacent plaits being corrugated or beaded to form spacers, the outer edges of the plaits of one Wall itting the corrugations in the opposite Wall., said units having offsets for spacing the units to form the Water passages.

6. ln a radiator construction, a, radiator unit comprising tvvo side Walls, two end Walls connecting the side Walls, each side Wall having plaits that extend across and abut the opposite side Wall, the plaits on the opposite side Walls being alternately disposed, the Walls between adjacent plaits being corrugated to form spacers for separat ingadjacent units, said plaits and corruga tions tapering in Width from their centers toward their ends, the plaits on the opposing Walls having their outer edges shaped for closely seating in the corrugations of the said opposite Walls, said units having oiisets for spacing the units to form the Water passages.
